I'll be the voice of disagreement, (please not too much hate) and say that I don't think to limit houses per account will necessarily fix the problem that people think it will - yes it will 'fix' one problem but it also hurts part of the community too. I do think limiting the number of FCs per account can help without punishing the players who choose to take the time to level multiple characters and enjoy the game through housing/rp/or whatever non-raiding form they choose. Reducing FC's per account addresses market manipulation for airship/workshop items and reduces the number of houses per character. Players would have to double their work to buy the same number of houses then since they could only get 1 FC house per account. Players take advantage of multiple FC's to have additional housing and to build walls/airship parts.
